A transition radiation detector for pion identification in the 100 GeV /c momentum region
/ Commichau, V ; Deutschmann, Martin ; Goddeke, H ; Hangarter, K ; Putzhofen, U ; Schulte, R ; Struczinski, W
A large area transition radiation detector has been proposed for the European Hybrid Spectrometer at CERN. Its construction is based on experience with a smaller size model detector which has been tested in hadron beams between 40 and 140 GeV/c momentum. [...]

Transition radiators for electron identification at the CERN ISR
/ Cobb, J (Brookhaven) ; Fabjan, Christian Wolfgang (CERN) ; Iwata, S (Brookhaven) ; Kourkoumelis, C (Yale U.) ; Lankford, A J (Yale U.) ; Moneti, G C (Syracuse U.) ; Nappi, A (CERN) ; Palmer, R B (Brookhaven) ; Rehak, P (Yale U.) ; Struczinski, W (CERN) et al.
The authors describe transition radiators constructed from thin foils of lithium, used to separate electrons from heavier charged particles at the CERN Intersecting Storage Rings (ISR). The optimisation of the system of the radiator and detector is discussed, leading to the choice of parameters for this design. [...]

The cross-section for $J/\Psi$ production in proton-proton collisions at center-of-mass energies between 23 and 63 GeV
/ Cobb, J H (BNL, NSLS) ; Fabjan, Christian Wolfgang (CERN) ; Goldberg, M (Syracuse U.) ; Horwitz, N (Syracuse U.) ; Iwata, S (BNL, NSLS) ; Kourkoumelis, C (Yale U.) ; Lankford, A J (Yale U.) ; Mannelli, I (CERN) ; Moneti, G C (Syracuse U.) ; Nakamura, K (CERN) et al.
The cross-section for J/ psi production in proton-proton collisions has been measured as a function of centre-of-mass energy at the CERN Intersecting Storage Rings by observing its decay into electron- positron pairs. This cross-section is found to rise by a factor of about six over the full centre-of-mass energy range from square root s =23 to square root s=63 GeV. [...]

The cross section for the production of massive electron pairs and the Upsilon (9.5 GeV) in proton-proton collisions at the CERN ISR
/ Cobb, J H (Brookhaven) ; Fabjan, Christian Wolfgang (CERN) ; Fowler, E C (CERN ; Purdue U.) ; Goldberg, M (Syracuse U.) ; Horwitz, N (Syracuse U.) ; Iwata, S (Brookhaven ; Nagoya U.) ; Kourkoumelis, C (Yale U.) ; Lankford, A J (Yale U.) ; Mannelli, I (CERN ; INFN, Pisa ; Pisa U.) ; Moneti, G C (Syracuse U.) et al.
Measurements of the cross section for the production of electron pairs with invariant masses between 4 and 8.7 GeV are presented as a function of the centre-of-mass energy ( square root s=28 to square root s=62 GeV) of the colliding proton beams. A significant excess of events is observed in the region 8.7 to 10.3 GeV; these are ascribed to the Upsilon (9.5 GeV) resonances and estimates of the production cross sections are given. [...]

Testing of FE Hybrids and Si detector modules for the CMS Tracker
/ Axer, M ; Beissel, F ; Camps, C ; Commichau, V ; Flügge, G ; Franke, T ; Ilgin, C ; Mnich, J ; Niehusmann, J ; Poettgens, M et al.
The innermost region of the CMS detector will consist of silicon pixel and silicon microstrip detectors. One microstrip detector module is essentially composed of three elements: a set of silicon sensors, a mechanical support structure and the Front End Electronics (FE hybrid). [...]

Tests of CMS MSGC Modules at PSI
/ Beaumont, Willem (Antwerp U.) ; Beckers, T (Antwerp U.) ; Bernier, Kim (Antwerp U.) ; Blum, Peter (CERN) ; Bouhali, Othmane (Antwerp U.) ; Boulogne, Isabelle (Antwerp U.) ; Bozzo, Marco (INFN, Pisa) ; Brez, Alessandro (INFN, Pisa) ; Buzulutskov, A (Novosibirsk, IYF) ; Coffin, Jean-Pierre Coffin (Strasbourg, IPHC) et al.
The CMS experiment, to be installed at the future p-p collider LHC at CERN, foresees the use of Micro-Strip Gas Counters ( MSGC's) for the outer layers of its central tracker. Present developments focus on the reliability of MSGC's in the harsh radiation environment imposed by the LHC. [...]
